BAKERS OVEN.

SPECIFICATION forming part of Letters Patent No. 396,395, dated January 22, 1889.

Application filed October S, 1888. Serial No. 287,508. (No model.)

To all 10.700712/ Z may concern.-

le it known that I, FRITZ DHRKOP, of New York city, New York, have invented a new and Improved Bakers Oven, oi which the following is a specification.

This invention relates to an improvement upon the bakcrs oven described in Patent No. 380,556, granted to me April 3, 1888. That patent describes an oven in which a hot-air space is interposed between the firechamber and the bakiiig-chamber. The tiroplace in said patent is located in the front part 'of the oven, and the heat is made to travel rst backward and then forward to reach the upright tlues. I n'ow propose to put the fire-place in the rear of the oven, as such a construction permits the free use ot' the oven by the baker without interference with the lire-place. In order to permit such au arrangement, I make the tire-chamber of T- shaped form, extending' tirst centrally under the hot-a-ir chamber and then branching to the righi and le'i't to connect with theupright fiues. An additional advantage ot this construction is that the oven can vbe built more solidly and compaclly.

The invention consists in the various i'eatures of improvement, more fully pointed out in the claims.

In the accompanying drawings, Figure l is a vertical transverse section ot' my oven on the lines ai a; and az az, Figs. 2 and l. Fig. 2 is a horizontal sect ion on line 1/ y, Fig. l. Fig. 3 is a similar" section on linc z .2', Fig. l; and Fig. l, a similar section on line A1c 1r, Fig. l.

The letter A represent-s an oven, having' a iire-place, d, that opens through the rear wall of the same. This fire-place a communicates with the nre-chamber b, extending centrally through the lower part of the oven and reaching up to the front wall of the same. Here the fire-chamber branches oit to the right and left, as at c c, so that the fire-chamber is T- shaped in horizontal section, as shown in Fig. 2.

The fire-chamber l) is spanned by an arched roof, d, above which there is located the hotair chamber e, situated beneath the floor fof the baking-chamber g. This floor f is supported by arches j, resting upon girders. The air-chamber e is considerably wider than the tiro-chamber b, and consequently extends to the right and left of the same, Fig. l. I-Iere the air-chambei.l is supported upon a -solid brick foundation, which gives great stability to the structure. The baking-chamber g is provided with a double-arched roof, t' fi', between which the partitions form a series ot' flues, 7u 7c. The outer fines, 7u', communicate with the' branches c of. tire-chamber b by means ot' vertical tlues l, placed in the right and left forward. corners of the oven.

The heat and products of combustion travel Vfrom the fire-place a forward through chamber l), and thence through branches c, up through rines Z.. From the flucsZ- the heat passes into outward iiues, k', thence around partitionsj, to central Hues, f, and iinally out of the stack fm.

' '.lhc heat radiated t'rom chamber l) heats the air in the air-chamber e, and the latter in tuin heats the bottom of baking-chamber g. I have found that though the tire-chamber b extends only underneath the central part.- of the airchamber, the heat radiatml from the iirechamber is ample to sufficiently heat all the air in the air-chamber. Thus a uniform degree of heat is imparted to the top and bottom of the baking-chamber.

What I claim isl.. The combination of a T shaped irechamber, l), having the fire-place a in the rear end ot' the oven, with the baking-chamber g and interposed air-chamber e., and with the upright lines I, communicating with the branches c ot' chamber b, substantially as specified.

2. The combination of a fire-chamber, b, having the tire-place in the rear of the oven, with a superposed air-chamber, e, which is wider than such iire-chan'lber, and which is solidly supported on both sides of the same, and with a baking-chamber, g, above the airchamber c, substantially as specified.
